The circuit represents a full wave bridge rectifier when switch \(S\) is open. The output voltage \((\text V_0)\) pattern across \(R_L\) when \(S\) is closed:
1. | 2. | ||
3. | 4. |
The peak voltage in the output of a half-wave diode rectifier fed with a sinusoidal signal without a filter is \(10\) V. The DC component of the output voltage is:
1. \(\frac{10}{\pi }\) V
2. \(10\) V
3. \(\frac{20}{\pi }\) V
4. \(\frac{10}{\sqrt{2}}\) V
If a full-wave rectifier circuit is operating from \(50~\text{Hz}\) mains, the fundamental frequency in the ripple will be:
1. \(25~\text{Hz}\)
2. \(50~\text{Hz}\)
3. \(70.7~\text{Hz}\)
4. \(100~\text{Hz}\)
